  1. Useful LJTicks for digital inputs and outputs are the LVDigitalIO, OutBuff, Divider, DigitalOut5V, and the RelayDriver
  2. The U3-HV and T4 have 4 dedicated high-voltage analog input lines that can't be switched into digital mode.

LabJack also makes several accessories to assist with common digital circuitry demands. Useful accessories for digital inputs and outputs are:

  • RB12 - Provides 12 industry standard relay module sockets.
  • PS12DC - Provides 12 optically isolated switches for power switching applications.
  • LJTick-LVDigitalIO - Bidirectional logic shifting board for communicating with digital circuitry at 3.3V, 2.5V, or 1.8V logic levels.
  • LJTick-OutBuff - Can be used to circuitry with higher current requirements.
  • LJTick-Divider - Useful for interfacing with higher voltage circuitry.
  • LJTick-DigitalOut5V - Converts 3.3V to 5V which is good for controlling relays.
  • LJTick-RelayDriver - Allows digital I/O lines to control a relay or other moderate loads.
